ICE-BREAKING DEVICE,

ratentecl May 29, 1906.

To all whom it may concern:

Be it known that I, JOHN H. DALE, acitizen of the United States of America, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Ice-Breaking Devices, of which the following is a specification.

The object of this inventionis to provide an inex ensive, portable, and efiicient device for brea ing ice for use in bars, hospitals, &c.

It comprises an organization involving two rotary ice-breakers, from the first of which the broken ice passes to the second, where it is further reduced in size. means of ad justment is provided whereby the ice may be reduced or broken into pieces of different size, as may be desired.

In the accompanying drawings, Figure 1 is a view, mainly 1n vertical section, on the line 1 1 of Fig. 2 with the sides of the hopper or receptacle for disintegrated ice broken away. Fi 2 is a front view in vertical section at rig t angles to Fig. 1 Fig. 3, a plan; Fig. 4, a section on the line 4 4 of Fig. 2 Fig. 5, an end elevation of the upper rotary member carrying ice-breaking points; Fig. 6, a plan of the .same broken away or in section at one point; Fig. 7 a plan, and Fig. 8 a side elevation, of the lower tooth-carrying or ice-breaking member.

The casing may be as shown or of any appropriate construction and comprises a hopper a at the top and a broken-ice receptacle]; at the bottom, the latter forming a base from the corners of which apertured lugs I) extend for the purpose of attaching the device to suitable support, as a table or shelf. At the base of the hopper and in suitable bearings formed in the sides of the casing or upper walls is mounted a shaft 0, with a key or feather. To one projecting end thereof is applied a crank-wheel d and to the other a beveled gear 6. To this horizontal shaft are keyed trefoil collars f, having three equidistant projections f, in the contiguous faces of which are formed seats f, in which are seated pointed ice-breaking teeth or picks 9, all pointing in the direction of rotation andv shown as arranged on lines tangential to circles struck from the axis of rotation. The several col1arseight being shown-are clamped to bind the picks g in their seats by three .bolts'and nuts h passing through the three projections f of each collar f. Byloosening the nuts the extent of projection of the teethzniay be adjusted. Opposite the pickheadgso formed and preferably slightly below the axis of rotation thereof are inwardlyprojecting teeth 2', mounted in the wall atthe base ;of the hopper and held by set-screws i or otherwise and projecting into the spaces between the teeth g. The front wall'of the hopper is preferably inclined, as shown, to direct the block of ice to the picks or teeth 9'. The ice broken by these teeth in pieces sufli ciently small will pass down between the horizontal stationary teeth 91, while pieces too large to pass will be broken between the revolving and stationary teeth. The beveled gear e meshes with a corresponding gear j on a vertical'shaft j, to which it is splined, so that the shaft may be vertically adjusted by means of nuts applied to its up or threaded end on each side of a bracket ll projecting from the side of the hopper. The shaft has its bearing in this bracket and also in a boss is, projecting upwardly from the casing and in a cross-piece k extending between the walls of the casing. Below the bottom of the hopper the casing inclines laterally, and at the bottom of the inclination is a circular opening m, the downwardly-extending walls of which flare outwardly and have formed upon their inner face projecting teeth n. the conical chamber thus formed and opening into the receptacle b is located a conical pick-head, which is shown in detail in Figs. 7 and 8. It is composed, as shown, of five separate sections or collars 0, applied to the reduced lower end of the shaft y' and clamped together by a washer-nut p, applied to the threaded end of the shaft. The several collars are of different radial dimensions, and each one has three projections 0. In contiguous faces of such projections are seats for the picks 9, arranged radially with reference to the axis of rotation and the projection of which maybe adjusted by loosenin the nut By adjusting the conical pic er-head vertically in the conical chamber m the picks carried by the head and the points on the interior surface of the chamber may be brought closer together or farther apart to break the ice to the desired degree. After passing the conical picker-head the ice drops into the receptacle"'b,"which is provided with a suitable sliding drawer 12 The receptacle may be composed of metal, cast or otherwise formed, and the drawer may be made of ordinary galvanized sheet-iron. The hopper andinclined part of the casing may be cast in one piece and bolted on the top of the receptacle.

I claim as my invention- 1. In an ice-breaking device, the combination of a hopper having an inclined wall at the base of which is disposed a picker-head revolving about a horizontal axis and having projecting teeth, a series of fixed teeth between which the teeth upon the picker-head pass, a receptacle for broken ice, a section of inclined casing extending from the base of. the hopper to the receptacle and terminating in a circular outwardly-flaring conical opening having ice-breaking teeth upon its inner surface, a tapered picker-head disposed in said conical chamber and carrying teeth proj ecting therefrom, a vertical shaft upon,

a which the lower picker-head is mounted,

bearings therefor, a beveled gear splined thereto and a corresponding'beveled gear on itlhe shaft of the horizontally-disposed picker-.

ead.

2. In an ice-breaking'devide,"thecombination of a hopper having an inclined wall at the base of which is disposed a picker-head revolving upon a horizontal axis and having projecting teeth, a series of fixed, teeth between which the teeth upon the picker-head pass, a receptacle for broken ice, a section of inclined casing extending from the base of the hopper to the receptacle and terminating in a circular outwardly-flaring conical opening having ice-breaking teeth upon its inner surface, a tapered picker-head disposed in said conical chamber and carrying teeth proj ecting therefrom ,a vertical shaft up on which the lower picker-head is mounted, bearings therefor, a beveled gear splined thereto and a corresponding beveledgear on the shaft of the horizontally-disposed picker' head, and means for adjusting the shaft of the tapered picker-head, for the purpose set forth.

In testimony whereof I have hereunto subscribed my name.
